Rosie, who was living with Daniel in his $4.3 million dollar Manhattan apartment, is crushed by the breakup, and her father said, "Rosie's not in this country at the moment. She's trying to move on. She won't want to talk about it."

But she's not the only one upset by the situation. Erin, 28, and Daniel are no longer together although they thought things between them were more than just a fling.

Life & Style reports: "Erin thought it was a real relationship, going as far as introducing Daniel as her boyfriend. He’s flown her out to London and taken her on dates and spent plenty of time with her in NYC, but Daniel just up and left New York without a second thought. Erin was devastated!"

Daniel and Rosie, a production assistant, have been dating since 2007, when they met on the set of Harry Potter and The Half-Blood Prince.
